The point of this class is to introduce you to the "engineering process." We'll do this by finding a common problem and attempting to solve it over the course of the semester. While doing this we'll also discuss many of the attitudes which an engineer needs to be successful.
Engineering Process
There are many versions but this is the one we'll use. 1. Identify the Problem 2. Identify Criteria and Constraints 3. Brainstorm Possible Solutions 4. Select a design 5. Build a Model or Prototype 6. Test the Model and Evaluate 7. Share the Solution
8 Refine the Design
Scrum

First day of class
Today we introduced ourselves and then took on an engineering challenge called Hang On Tight! You were given 1 golf ball, 2 pieces of paper, 2 pieces of string 24" long, and 2 pieces of scotch tape 24" long. Your objective is to get the ball as far off the wall as possible without using the ceiling, floor, or anything other than the wall.

Today we broke open the box of cubes and went to town. Individuals either took measurements from grain-to-grain, or they sketched in their Engineering Notebooks the various configurations for putting together 1 cube, 2 cubes, 3 cubes, ... up to 6 cubes. Mr. Nystrom set up and shared a Google Folder and placed a spread sheet in it which each student will post their measurements to. Homework was to finish drawing ... though after you get a bunch for the 6 cubes you can challenge yourself to get them all ... or call it quit's after 8 or so variations.

The plan today is to spend a short period of time decorating our cube display. We will also develop a general progression of events using MindNode or OmniGraffle. Our objective is to work together to come up with a general idea of how to make our wind tunnel. We also need to agree on the parameters which should include: cross sectional area, flow speed, digital acquisition measurements, size and budget constraints. Any questions on the Low Speed Tunnel pdf?
First draft of "what needs to be done" using MindNode. Wind Tunnel- MindNode.mindnode
Homework is to determine the test section requirements: This has to fit a Maine Wind Blade challenge blade and a rocket in cross section. Gabe, Marc, Vasily, and Matt are on this team. We also established a DAQ team of Ryan, Stearns, and Zach. Leaving only Quinn on the Overall design.

Today we're going to break into CAD: AuttoCAD Inventor specifically. Your task will be to draw all of your blocks and put them into an assembly. Doubt we will have the time, but if we do we'll carry this into the drafting side of the program.
We also need to discuss last class's assignments: the size of the test section, and see what kind of Gant Chart Quinn has developed.

Happy Halloween. Today we're going to discuss the conservation of mass were we discuss the relationship between cross sectional area and velocity. Do this short worksheet problem (print it off at the bottom of the page). I'd like to do a short derivation of Bernoulli's principal on the board. We'll end the day working with this wind tunnel simulation from NASA.
It's worth noting that we now need to know what the velocity and dimensions should be of our test section. Consider reading some of the following:
